​MasterRheobuild 561 - A superplasticising admixture to produce low slump loss rheoplastic concrete

How does MasterRheobuild 561 work?

MasterRheobuild 561 is specially designed to impart low slump rheoplastic qualities to concrete. It ensures that the rheoplastic concrete remains workable for up to 3 hours at 20°C and 1 hour at 40°C. The workability loss depends not only on temperature, but also on the type of cement, the nature of the aggregates and the method of transportation.

It is chloride free and meets the requirements of ASTM C494 Type D and G, SS EN 934 for set retarding/high range water reducing/superplasticizing admixtures.

What makes MasterRheobuild 561 a unique solution?

Rheoplastic concrete is a fluid concrete, easily flowing but at the same time free from segregation and having the same water/cement ratio as that of a no-slump concrete without admixture.

How can you benefit from MasterRheobuild 561?

MasterRheobuild 561 is compatible with all cements meeting recognized international standards.​ It offers high workability result in short placement time and helps to save project time and labour resources.

It also provides good cohesion that reduces segregation to the concrete mix. It helps to ensures good homogeneity whilst maintaining workability thus improving the finishing characteristics.
